I originally bought this to help me upgrade my Telecaster guitar electronics but found I didn't really need it for that. It was great to have an LED for a pair of front and rear cameras on the car. For example, when the Workbench Mini hangs on the resistor of the LED and puts a slight tension on the mechanical connection so that the components coil up when soldering. before you stay where you want them. It's impossible to get it right with two hands. The included removable terminal end caps come in handy for protecting sensitive parts. The magnets in the mounts hold them securely to the base. A very good thing. By the way, if they're sold with just two alligator clips, they should be called "two-handed" and not "quad", right?
